STRETCHER FOR CASE SKINS.

Application filed April 18, 1923. Serial No. 632,979.

T all whom t may concern:

Be it known that I, SAMUEL FRIEDMAN, a citizen of the United States ofAmerica, and a` resident of the city of New York, borough of Brooklyn,in thecounty of Kings and State of New York, have invented a new andImproved Stretcher for Case Skins, of which the following is adescription.

My invention relates to stretchng what are known as case skins, that isto say, skins into which the stretcher elements may be inserted and thenseparated to stretch and enlarge the case skin. .The means generallyemployed for Vstretching case skins are mounted on the top of the tableand the supporting base and other parts appurtenant to the stretcheroffer vmore or less of an obstruction on the table and limit theclearance space above the table so thatthe Operator is required to havea considerable reach over the table for the placing and removal of theskin and for actuating the movable stretching element.

The general object of my invention is to overcome the objectionableconditions referred to and tins object I accomplish by providing aconstruction in which the supporting base of the stretcher is securedbeneath the table and the-stretcher elements have a form to extendgttivardly, upwardly and then laterally inwafd to overlie the table.35.:

A further objec fof vmy invention is to provide an operatno means forthe movable stretcher element disposed for the main part beneath thetable and having an arm projecting laterally outward to be disposed inposition for the operator to lean against the the application of thepressure to the operating means.

A more specific object of the invention is to provide for foldingthepressure arm of the operating means to an inner position when not in useso as not to oder an obstruction materially beyond the table edge.

Reference is to be had to the accompanyy* ing drawings forming a part ofthis speci. fication, it being understood that the drawings are merelyillustrative of one example of the invention.

Figure 1 is a plan view showing a portion of the table equipped with myimproved stretcher and operating means therefor;

' Figure 2 is an enlarged inverted plan view of the stretcher andoperatlng means as applied to the table;' l

Figure 3 is a front view of said stretcher` as applied to the table;

Figure a is a transverse vertical section as indicated by the lne 4 1,Figure 3. .In carrying out my invention in accordance with theillustrated example, 1 provide along the base and the other leg oftheV Uextending laterally inward and overhanging the table top a properdistance above the latter,whereby to provide stretcher arms 14, on therespective elements 12, 13,. The fixed element 12 is securely bolted orotherwise suitably fastened to the .base plate. The movable stretcherelement 13 is adapted to slide on two parallel guide rods` 17 supportedon the base 10. i

For operating the stretcher element 18 use is made of a lever 18disposed beneath the table top and fulcrumed at its inner end as at 19to a corner of the base 10. A link 20 is riveted or otherwise fastenedat one end as at 21 to the stretcher element 13 and at the opposite endsaid link is secured by a bolt 22 to the lever 18, the link beingprovided with a longitudinal series of bolt holes 23 for adjusting thethrow of saidrelement 12. One end of the lever 18 is in the form of apressure arm 24: pivotally mounted at the inner end as by a rivet .25.yThe arm 24 when the machine is to Abe operated is swung to a positionprojecting laterally outward beyond the table top A but the pivot 25permits of the arm being folded inwardly adjacent the edge of the tables0y as to offer no obstruction. ment of the army 24 to theouter positionis limited by providing on the main section of the :lever and on thevsaid arm 24'shoulders 29 and 8O respectively. A retractile coil spring26 is secured at one end to a lug 27 or other fixed part of the frame1() and the other end of said spring is secured to a lug 28 or otherfixed part of lever 18.

`With the described yconstruction when the arm 2d is swung to the outerposition as indicated in Figures 1 and 2, the operator of The pivotalmovethe stretcher may lean his body against said arm andby exertinglateral pressure on the arm swing the lever 18 on its fulcrum 19 andthereby through the link 2O moving the stretcher element 13 aivay fromthe element 12 thus separating the stretcher arms 14, 15 and extendingorV stretching the skin that has been slipped onto said stretcher armsor juxtaposed as in Figure l. Upon the operator removing the pressureagainst the arm 2a the spring 26 restores the lever 18 and the stretcherelements 12, 13 to the original positions. It will be seen that when thedescribed stretcher is emplaced on the table only the stretcher arms 14,15 Will be disposed over the table, the remainder yof the surface of thetable affording clearance for' the skin and for the movements of theoperators hands and arms inthe operation of stretching. The constructionresults also in the stretcher arms 14, 15 being disposed close to anedge of the table instead of being emplaced laterally inward from thetable edge as is usual. The nearness of the stretcher arms to the edgeof the table greatly promotes convenience in the placing and removal ofthe skins.

I Would state in conclusion thatY While the illustrated exampleconstitutes a practical embodiment of my invention, 1 do not limitmyself strictly to the exact details herein illustrated, since,manifestly, the same can be considerably varied without departure fromthe spirit of the invention as defined in the appended claims.

Having thus described my invention, l claim:

A stretcher device including stretcher elements having means thereonat their lower portions in a plane to secure the same beneath a tabletop and including members ex tending laterally outward from theirconnection With said securing means, then rising from said outwardlyextending portions and then directed laterally inward from the risingportions in a plane sufficiently above the securing means to lie abovethe table top.

2. A lstretcher of the class described adapted to be disposed adjacentto an edge of a table and comprising fixed and relatively movablestretcher elements having members to overlie the table as Well asdownwardly extending members at the outer ends of the first mentionedmembers, and members y extending laterally inward from said downi wardlyextending members in a plane to lie beneath the tabletop, and means tosecure the said inwardly extending members beneath the table top;together' with actuating means for the relatively movable memberspositioned to lie With the securing means beneath the table top.

A stretcher of the class described adapted to be disposed adjacent to aside edge of a table and comprising fixed and relatively movablestretcher elements having members to overlie the table as Well asmembers adapted to extend beneath the table top, means to secure thesecond members beneath ythe table top, and actuating means for themovable element, said actuating means including an element operativelyconnected with said ino-v-y of the class described neath the table,means :to secure the secondy y mentioned members beneath the table top,and operating means connected.
